Cost challengeCommunity infrastructure = increased cost
Capital costs ($/ha)– Scheme (off farm) $5,000 - $12,000 – On-farm irrigation $4,000 - $10,000– On-farm development ?
Water Charges ($/ha)– Interest & Principal $700 - $1,700– Scheme operating costs $100 - $500– Total $800 - $2,200
Additional gross profit required = $1,000/ha

Making irrigation pay
• Adding water alone not economic
• Need to intensify farming system– Higher stocking rate– Higher crop yields– Store => Finishing
• Irrigation development = rapid change in land ownership and farming systems -– Livestock => intensive cropping– Livestock => dairy farming– Mixed cropping => viticulture or horticulture
![Page 8: Irrigation NZ “Promote Excellence in Irrigation” Advocacy & Leadership Education & Training Research & Innovation Membership Schemes, User Groups & Individual](https://reader030.vdocuments.us/reader030/viewer/2022032606/56649e8a5503460f94b905f7/html5/thumbnails/8.jpg)
Major hurdle - can I intensify?
• NPS Freshwater Management 2011
• Values, objectives and limits for quantity & quality
• Allocation for water & nutrients
• Irrigators need demonstrate operating to a standard – Good Management Practice
• Accountability – Auditable Farm Environment Plans
• Creates additional cost to Business-as-Usual
